The present invention is not limited thereto, and all switches capable of selecting a predetermined device among a plurality of devices may be applied according to the operation type and the number of operations. In addition, the number of each switch varies with the number of distributors, pipes, and indoor units.

As described above, after the distributor switches RS1 and RS2, the pipe switches DS1 to DS4, and the indoor unit switches SW1 and SW2 have been operated, the pipe switches DS1 to DS4 which have been operated are returned to their original states, and the respective pipe switches When all the same state, a signal indicating the completion of the setting for the pipe is applied to the control unit 1 (S130). At this time, the control unit 1 matches the indoor unit to the piping of the distributor corresponding to the pre-stored distributor number, the pipe number, and the indoor unit number in response to the signals input from the pipe switches DS1 to DS4, and the data is matched with the data unit. (5) (S140).

For example, the 2nd distributor 22 is selected and input from the indoor unit matching part 3 by the 2nd distributor switch RS2, and the 2nd distributor 22 of the 2nd distributor 22 is operated by operation of the 2nd piping switch DS2. When the second pipe is selected and the second indoor unit switch SW2 is operated three times, and the third indoor unit 33 is selected, when the operated second pipe switch DS2 returns to its original state, the control unit 1 The controller determines that the third indoor unit 33 is connected to the second pipe of the second distributor 22 according to the signal input from the pipe switch DS2, so that matching data is stored accordingly.

Here, it is determined whether the matching is completed for all the distributors 20 and all the pipes (S150). When the matching setting is not completed, the above process is repeatedly performed to complete the matching between the distributor and the indoor unit (S100). To S150).

When the matching is completed for all the distributors and all the pipes, the final matching data is stored in the data unit 5 and simultaneously transmitted to each distributor 20 (S160).

Each distributor 21 and 22 controls the refrigerant supplied to the indoor unit based on the matching data received from the outdoor unit 10.

Therefore, when automatic search fails for at least one distributor pipe / valve, setting can be manually input through the indoor unit matching unit 3 so that a matching setting can be established between the distributor and the indoor unit, and even after the air conditioner is installed. It is possible to change it manually, so it is easy to check and change the setting even if the pipe is connected incorrectly or there is an error in the matching data.

As described above, the air-conditioning simultaneous multi air conditioner and the pipe setting method according to the present invention have been described with reference to the illustrated drawings, but the present invention is not limited by the embodiments and drawings disclosed herein, and the technical concept is protected. It can be applied within the range.

Simultaneous air-conditioning type multi air conditioner and piping setting method of the present invention is provided with a plurality of switches in the outdoor unit to enable the selection of the distributor, piping, indoor unit, by manually matching the piping and the indoor unit of the distributor, There is an effect that pipes are incorrectly connected between the distributor and the indoor unit, or malfunctions due to mismatches can be prevented, and convenience of management can be improved by easily checking and changing the connection state.
